KP2744-364A5356 - Lincoln Magnum PRO Copper Plus Contact Tip 3/64 Aluminum 5356 (10-Pack)

High-Performance Contact Tips for Aluminum Welding

The Lincoln Electric KP2744-364A5356 is a specialized contact tip designed for industrial fabrication environments utilizing the Magnum® PRO MIG gun platform. Engineered specifically for 3/64-inch (1.2 mm) 5356 aluminum wire, this consumable addresses the unique thermal and mechanical challenges associated with continuous aluminum welding. The tip features Lincoln's proprietary Copper Plus® technology, which utilizes a larger outer diameter to increase the total copper mass. This additional mass significantly improves thermal conductivity, allowing the tip to disperse heat more efficiently than standard diameter tips. In high-duty cycle applications, this heat management is critical to preventing micro-arcing, burn-back, and premature tip failure.

Beyond thermal management, the KP2744-364A5356 incorporates Anti-Seize™ Threading technology. The thread profile is engineered to resist deformation under the extreme thermal cycling inherent in welding processes. This prevents the contact tip from fusing or seizing to the gas diffuser, a common issue that can lead to costly downtime and damage to the MIG gun front-end assembly. The bore of this specific SKU is precision-machined to tolerances optimized for 5356 aluminum alloy, which has different stiffness and thermal expansion characteristics compared to 4043 alloy or steel wires. This ensures consistent electrical contact and smooth wire feeding, essential for maintaining a stable arc in aluminum MIG welding.

Rated for currents up to 350 Amps, these contact tips are suitable for medium to heavy-duty fabrication tasks. They are supplied in a pack of 10, ensuring that operators have sufficient inventory for production runs. By integrating these high-performance consumables into your welding system, you ensure that the Magnum® PRO gun operates at peak efficiency, delivering high-quality welds with reduced maintenance intervals.
